You know that the price of the car when Mariah purchased it was:
![$8,599$\text{ }dollars](https://img.qammunity.org/2023/formulas/mathematics/college/awavz9jo0r2ashfupwmbv1f1gqdhc52jyd.png)
And you also know that the rate of depreciation is 2.5%.
Then, you can use the following formula to calculate the Depreciation Value:
![A_n=P(1-R)^n](https://img.qammunity.org/2023/formulas/mathematics/college/514hbk1pnrxg5dm00zuwg7fmuati7s47fo.png)
Where "P" is the initial value, "R" is the depreciation rate (as a Decimal number), and "n" is the number of periods.
You can identify that, in this case:
![\begin{gathered} P=$8,599$ \\ \\ R=(2.5)/(100)=0.025 \\ \\ n=4 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/mwxfbsikexlk2qeyxyrqza5iubtnd1exso.png)
Then, substituting values into the formula and evaluating, you get this result (in dollars):
![\begin{gathered} A_n=P(1-R)^n=($8,599$)(1-0.025)^4\approx7,770.81 \\ \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/358e90vpi7n5c5ofe0v2l0b3re1hx41lof.png)
Therefore, the answer is: Last option.
